It is pretty much the same as the main model (the sports car) but I changed the roof position and it completely changed to type of car it is. From a modest little sports car to something like an SLS AMG or Dodge Viper. I'm pretty happy with the way it looks and I refer it over the standard model, plus it's super simple to do.
The only gripe I have is with the design of the windshield, it causes part of the window to cover the door panels, but it isn't that much of an issue
